Jason,

I'm very afraid the problem still exists. I cannot see any difference
within my test application.

At application startup, the grid is not visible. Switching to
TabSheet2 and back to TabSheet1 makes the grid appear.

Here is what I've done:

1. Completely deinstalled IBO and removed all files IBO*
2. Unzipped IBO_4_2_E.zip
3. Unzipped IBO_4_2_Eg.zip into the same directory
4. Unzipped Patch4Eg.zip into the same directory
5. Recompiled and installed everything
6. Recompiled my test application

I didn't install TestPatch_42Eg_1.zip from your download site (is that
correct?).

My test application consists of only 1 form and 1 unit file (2 lines
of code). Don't you really want it?

Sorry for this negative reply.

Regards,
Mario
