I have (had) the same problem!!!
It happened with checkboxes and grid, as soon as I check/unceck it and chan=
ge row, or when I commit.
I tried to isolate the problem, but nothing.
I tried to make a minimal demo app, but I can't reduce complexity and keep =
the problem alive.
I've made a series of patches to IB_Grid TIB_CustomCombo.Destroy and Update=
bar, to reduce system resource and make objects be better free.
Now the problem is disappeared, but I don't think I've fixed it, only avoid=
ed some of it's bad behaviour, or pushed the problem a little far.
Hope that Jason will integrate my patches into IBO.
If you want, give me your complete e-mail privately and I sent you the sour=
ce.
I use Delphi 6 pro SP1 (and SP2, but same problem), and you?
Regards
Marco Menardi
