QCAD.org Forum

I have a registered version of QCad Pro. For approximately the last 4 to 6 months, when I'm using it, I'll click to move/modify/layer/ etc and the program just closes. No warnings, no error messages, nothing. It just closes and I lose whatever I've been working on unless I save it every time I change anything. Any possible explanation as to why this is happening?
Also I've uninstalled and re-installed twice. I'm running it on XP Professional SP3Intel Core 2 Duo CPU, T7500 @ 2.2GHz, 2GB RAM
