I seem to have a memory leak associated with tool tips. When ever I place the mouse over a panel using tool tips I cas see the dynamic memory usage continuously increasing. If I comment out the call to the tool tip functions (i.e. SetCtrlToolTipAttribute), the memory leak dissapears.

There's no patch for 8.0.0, if that's you mean. But since the Programmer's Toolbox is open-source, you can easily fix it yourself: In line 3365 of the 8.0.0 version of C:\Program Files\National Instruments\CVI80\toolslib\toolbox\toolbox.c, you need to add the following ListDispose function call: if (RectContainsPoint (bounds, point)){ PointConvertCoordinates (panel, child, &point, FALSE); ListDispose (sortedChildren); return PointToPanel (child, point);} After you make the change, you'll need to recompile the file (Options>>Create Object File) to regenerate the object file, and then restart CVI.

tool tip memory leak

Solved!

Thanks, that worked. I should have seen it, but I invoke gcc directly much
less than I call makefiles written long ago...
