Konqueror slow

Suse 7.1 kernel 2.4.17 kde 2.2.2 XF86-4.2.0 I am trying to diagnose a problem with konqueror. It suffers from a delay when trying to move around the filesystem and moving from window to window. For example if I click on a directory -have a look -then want to go back, by clicking on the back button in the menu bar, I have to wait a second or so for it to happen. It is as if I have to wait for the mouse to activate the menu bar. I tried reinstalling it but this has not achieved anything. This is perculiar to konqueror and in not the case with other software. Has anyone come across this ? I like konq and would like to make more use of it. Brian Marr
