Sluggish gnucash

I upgraded to openSUSE 11.0 with KDE 3.5.9 and installed gnucash 2.2.4. When I click on a tab, the response time in opening that tab is at least two to three seconds. I didn’t experience this type of sluggish reaction in openSUSE 10.3, KDE and gnucash 2.2.0.

Has anyone else experienced this problem? If so, do you know of any remedies?
