Problem: superimposed BMPs in Tree

In Windows 8, Tree images, BMPs with a 'transparent' (RGB=192,192,192) background, seem to be superimposed. After temporarily switching to a different tab they appear as they should. This problem did not occur in Windows XP. Is this something that can/will be fixed or should I no longer use 'transparent' BMPs?

Can you reproduce the effect with other image =list images, or is it only happening with the tree control?

Only the tree control is affected. See the new test files.

The new ODCL includes:

  • Tab Strip

  • Tree Control

  • Grid

  • List View

  • Picture Box

  • Graphic Button



Notes:
1.
Changing the image list for the tab strip conflicts with the correct display of the tab content. You will have to uncomment some code to see the images changing.
2.
Studying the Grid.lsp sample I noticed that some of the functions used there are deprecated.
