Description Vadym Krevs 2006-04-04 23:48:20 UTC

Version:           3.5.2 (using KDE 3.5.2 Level "a" , SUSE 10.0 UNSUPPORTED)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.13-15.8-default

Konqueror is exremely slow when accessing the Outlook Web Access web interface to MS Exchange. When I right click over this text area (on http://bugs.kde.org/wizard.cgi), the context menu appears instantaneously. On the other hand, when I right click over the text area in "new email" in Outlook Web Access, the context menu takes 2+ seconds to appear. Any operation like typing a single character into the To: or Subject: text boxes takes a second or more and is accompanied by a CPU usage spike. Needless to say that Firefox does not have this problem. The source of the frame is below.
