I have a client for whom I had be running the non-factory backport of KDE3 as we upgraded them past ... what was it, 11.0 was the last release that included it natively?
I've recently upgraded them to 12.1, and gone back to the OpenSUSE supplied KDE3, but while nearly everything works, I had two problems, which could be related.
We're using Xvnc, and the current Xvnc server program, supplied by xorg-x11-Xvnc-7.6_1.10.4-36.2.1, wouldn't work properly; IIRC (it's been a couple months), it started, but we couldn't reliably connect to it. So I fell back to the old old old one I'd originally set up with, and it's working fine with that... with one small exception.
When working in the KDE desktop, it's apparently impossible to drag and drop items, in the expected standard manner. Draggable things can be grabbed, and they will appear to drag, but *nothing* is a valid drop target: when he drags an item over what ought to be a drop zone, the zone does not highlight, and the cursor does not change from it's Generic Document cursor.
Additionally, when he clicks on a URL in an email in Thunderbird, nothing at all happens.
I have an intuition perhaps this is a version incompatibility in the inter application communication stuff, driven by the out of date Xvnc? I'm going to work on trying to get the new version to run reliably, today, but if anyone has any suggestions on what else might be causing this, or even how to diagnose it well, or where else to ask, that'd be great. :-)
