When used on multipage excel userform igrids are not consistent.
After opening of userform igrid control looks OK.
Switching to other page igrid on that page is not OK.
Most times switching through pages will crash excel.

Thank you for trying out the new 64-bit iGrid! Yes, we expect that there may be various issues since it is a new product created with a new development environment (twinBASIC).

But we and the author of twinBASIC, Wayne Phillis, are ready to investigate any issues and fix them. Can you send us a sample to reproduce this issue?

I have attached a simple userform ("test_igrid_64") with 2 pages.
On page 1 is an igrid control.
Page 2 is empty.
Userform will start up on page 1.
Switching to page 2 and back will show wat happens.
Headers disappair, table isn't browsable anymore and finally fault code.  Multipage_example.zip (2,132kb) downloaded 16 time(s).

At the moment, just a short confirmation that we've reproduced the issue. Give us some time to investigate it.

An update. Wayne Phillips implemented the fix for this issue in one of its recent releases of twinBASIC. However, we see some issues with the input focus when iGrid is inside a MultiPage control. We would like to fix all these remaining issues first and then provide a new build of iGrid for testing.
