Hi,

One of our applications is crashing sometimes when up to four maximized forms are shown (only if skinning is enabled), so I created a small test case to reproduce it and apparently it happens albeit not as frequently (the app is very heavy).

The test code consists of four forms with WindowState = wsMaximized; the first three have a button to open the next form; that's it. Sometimes. when I click to open the third form, the second form loses focus (title bar changes color) but the the third form is not shown and the program gets stuck, as well as any other program I try to open from the task bar: I can click them, but the programs only open after I kill the test app from the task manager. If I'm running it inside Delphi, even a breakpoint on the “begin” of the OnClick event handler doesn't get reached.

I´m using Delphi 7 Professional Build 4.453 and Alpha Controls 10.26 (tested with 10.25 and 10.19 with same results), W7 Pro/64.

Attached is a ZIP with test code, images (before and after error) and executable.

I don't have Delphi 7 installed so I tested it with Rad Studio 10 Seattle and Windows 10 Pro

I made a Demo with 10 Forms and Skin and opened it many times everything work well without problem.

Sorry I don't know about Delphi 7, Someone else should test it.

You can try remove AlphaControls and Delete all its files then reinstall it again.

Sometimes it can help.

Hello, Ronaldo!

Can you save an information about your system using the msinfo32 tool and send it to support@alphaskins.com?

I can't repeat this problem using your Exe (Windows 7 x64), I will search a system where it's repeated.

Whatever it was, it seems that version 10.27 fixed this problem.

Thanks! 🙂
