Hi all,

I subclassed VFP controls to several levels. First of all, I subclassed native vfp control to root_classes.vcx, and then I have base_controls.vcx, special_controls.vcx, and ingrid_controls.vcx. The controls inside special_controls and ingrid_controls are derived from either controls in themselves or from base_controls or mixed of both. I also have base_forms.vcx that utilize all three controls (base, special, and ingrid).

Problem is I often get a C5... error whenever I save a form (scx) or a form inside base_forms.vcx. Most of the time, it's only a simple C5 error. I was (forced) to get out of VFP and then when I launch VFP again, all my files are OK. But, yesterday, I got this C5 error and found that my base_forms.vcx are gone! Can you imagine that? _all_ my forms are derived from this class. Luckily I have back ups, but I still loose about twelve hours of working.

I use VFP8 SP1. I don't know how to re-generate the error intentionally, but most often this happen when I do a lot of back-and-forth between editing some forms in base_forms and the scxs. The only way I found is to implicitly put CLEAR ALL and RELEASE ALL in VFP's Command Window right before I run or edit the scx.

Anybody got this behaviour as well? Can anybody give me any insight about this matter?

Thanks in advance!
