OK, this is getting real strange now.
There are 6 Events in the Textbox class (BTW it's a VFX framework) and I have put code in each event to stop it executing the class code.
I've narrowed it down to something occurring in the Valid Event, I have:
SET STEP ON
NODEFAULT
As soon as NODEFAULT has processed - it clears the SelStart property in a flash, no code runs or anything.
This happens in the VFP Base Class AND the VFX Class.
BUT - it only happens when there is a ControlSource specified.
Any ideas?
Thanks
Kev
