--- Comment #3 from Igor Tarasov tarasov.igor@gmail.com 2008-04-21 16:54:48 --- I use control spy 1.0.
1. Launch status bar.exe 2. Select SB_SETTEXT message 3. Copy this text (within quotes) "a z" 4. Replace "string" (leaving quotes) with the text from clipboard 5. Click Send.
When running native comctl32.dll you'll see that a and z are at the left and right corners of status bar correspondingly. When running builtin comctl32.dll you'll see only two squares at the place of this doubletab.
I don't have control spy 2.0, installing it right now.
