There should be two tabs in the Taskbar at the bottom.
AIBFS tab should be highlighted.
Click AIAstar tab.
The AIAstar tab does not highlight. But the AIAstar window is active. AIBFS tab is still highlighted. This is not right.

Thanks for the report can you attached a screen shot?

It happens, but I cannot be sure to reproduce it reliably. I notice that the tab can have delays in highlighting.

We will rewrite this tool and we know it has problems but they are difficult to fix.

If I click the tab three times it always works. Perhaps that could be a workaround. Which method should I debug in?
