There is another possibile reason for multiple email downloads,,,,,
The symptoms are....
email downloads very slowly (at dsl speed 384 to 512kps 8 meg file takes 10- 15 minutes or more)
files and programs may give eratic operation (file or menu will not open when clicked)
a time out on the email server and the downloaded email is not cleared from the email server as being sent (it is not removed from the server), so it is resent as new mail.
It is caused by...
a program or programs accessing the computer cpu at the same time that incredimail is trying to get email.
Some POSSIBLE work arounds....(these are not neccesarily a fix) READ ALL BEFORE DOING!
1) While incredimail is running and trying to retreive email, open task manager (ctl, alt, delete) and select the tab for processes. At the bottom of the window click on show ALL processes. Look at the numbers in the column next to each description. These numbers show the percentage of CPU time that the program is using. Any high percentages (85-99 percent) will show which particular process is hogging computer time. Highlight the offending process and right click with the mouse. You will get a menu of selection for what to do. Select end process. You will see a warning that ending the process can cause problems. Select continue to end the process ( a windows critical process will not allow you to end a critical process so this is a Fairly safe method to use). The process will usually show you which program it is from so you need to remember which program ran the process so that you can take corrective measures (such as removing the program or taking it out of your start up files. Make sure that you can re install it later if needed). Do not forget to restart the computer when you are finished with the corrective measures.
2) Open msconfig (click start and in the run box type msconfig and <enter>). In the window select the startup tab. At the bottom of that window select the box that says "hide all microsoft services". Uncheck the boxes on all of the non microsoft start up programs and click apply (this turns off all of the added programs from startup without removing them from the PC). Restart the computer and try using Incredimail again.( There will be a message that states that you have changed the settings in msconfig, which you can safely disregard for the moment). You should notice a marked improvement in the download speed. You may get a final set of reprints of the emails on the server but if the problem has cleared up this should be the last time you get reprints or copies.
You will need to open msconfig (use the method described above) and turn on each disabled program( put a check in the enable box) one at a time until you find which program is causing issues with incredimail. You can then choose to remove the program or adjust its settings so that it does not automatically start up when the computer is turned on.
My issue with multiple emails resulted from Incredimail trying to download email through a USB wireless connection and APC power chute was running on another USB port. Powerchute hogged the USB port and would not let Incredimail down load at a sufficient speed so the server for Incredimail timed out. Removing powerchute appears to have corrected the issue for now, but I am not sure if there is some type of issue in Incredimails program or in power chutes programming. It does not appear to have diminished the speed of other programs that use the internet so there may be a file sharing or resource sharing issue that caused this problem. That is for others that know more to look into and fix.
