Im not sure what is going on. I run my setup and In the Customer Information Dialog, the radio buttons sometimes disappear. If I click where they should be, they show back up with the one I clicked. Also, sometimes the whole bottom have of some of my dialogs just aren't there. Again I click where there should be a button and the event still happens. So everything works, but some things just don't "show". What is going on?

I had similar trouble lately. All I can say is that deleting the controls and recreating them seems to eliminate the problem.

I had a similar problem with RadioButtonGroup-Boxes: When the boxes had an overlying text control, sometimes this text control was not visible. I couldnt find a reason why it was sometimes visible and sometimes not. I changed the size of this group boxes and rearranged the (text-)control on my dialogs so that there were no overlapping pieces. This helped till now.

The difference between theory and practice is larger in practice than in the theory.

I'm seeing the same problem on the standard unmodified LicenseAgreement page in IPWI 2.03. The upper radio button text disappears when clicked on and reappears when the lower button is clicked on.

I've tried deleting the radio group and radio buttons then recreating them but this made the problem worse - previously only the text would disappear but now the radio button disappears to.

This problem only seems to affect some machines. I've seen it once on a Windows XP machine, it is repeatable on one Windows 2000 machine but not another.

Are there any other tricks?

The tab order of the controls could be causing a background control to get painted over other controls. See InstallShield KnowledgeBase article Q106604.

We had encountered the same problem, but we had a billboard executing in the background when most of the controls especially the radio buttons were not visible until we had focused them (radio buttons).

We had to remove the Billboard to overcome the above problem.

Ah, we've got a billboard running in the background too. I shall try turning it off to see if the problem goes away.

Thanks for the advice everyone.

Yep... I found that getting rid of the billboards fixed everything.... oh well, those weren't really NEEDED anyway.

the problem with RadioButtonGroup is the following (took me a few hours to figure out...)

When you have a RadioButtonGroup WITHOUT a border, MSI creates it with BS_OWNERDRAW
if you set HasBorder to TRUE, it is created with BS_GROUPBOX

so setting HasBorder to TRUE removes all refresh problems, or you handle the REDRAW request by yourself
