Exception in CXTPControlEdit::SetEditHint

Hi,

I have received several crash dumps from my application with the following stack trace:

Here's the first frame with local variables:

00 0012e58c 78a3edcd ToolkitPro1342vc90U!CXTPControlEdit::SetEditHint+0x47 [c:\winappsrc\trunk\xtp1342\source\commandbars\xtpcontroledit.cpp @ 586]
0:000> dv
           this = 0x01599790
   lpszEditHint = 0x78a3f97c "맩???"

When I dump this, it seems to be invalid, and lpszEditHint is obviously invalid.

I use CXTPControlComboBox in a few places, but I don't ever set a "hint" on any of them.

Is this a bug, or am I doing something wrong? Seems that it's only been happening since upgrading to 13.4.2.

Thanks,
Drew

	Another thing I should mention is that so far all of these crashes are reported on machines running Windows XP SP3.
