I upgraded to 7.6.1-rc to get around the issue with template parameters and found that Multi-state indicators and pushbuttons and a few other objects can not be added to a window. Here is the code generated.

This was a bug introduced in 7.6.1rc2 and solved in 7.6.1rc3 that affected quite a few components being dropped in the desginer. Update to rc3 and you should be fine.
