Version: (using KDE 3.5.9) Installed from: SuSE RPMs OS: Linux My IMAP setup works some time after I start kmail (via kontact). But after a while not using the mail, kmail hangs somewhere during periodic check of mail. The progress indicator is stuck with some number, which is sometimes negative! (often -1%). Which is worse that the stuck operation cannot be aborted by clicking on the close button of the progress dialog. It then just says "aborting" forever. I think the problem might be caused because of my wifi connection to net, which is not too reliable. But TCP layer and kmail should cope with that. The severity could be crash because it is needed to restart program to work again.
Could you please give us more information about your setup? Is the problem still valid? Is there perhaps some useful console output?
My setup changed, I am connected via Ethernet now. Also I can not remember now how often the problem occurred. I did not have an Internet connection for last three months.
Having unstable wifi connections sometimes too, but never hangs in KDE 4.3.
