This issue is not present when I run from pbl, but only found while running on runtime (pbd).
There are some treeviews (pfc u_tvs) where the treeviewitems are not displaying, event though they are present (hoovering over them shows the tooltip). Clicking in the treeview control may get them visible. But clicking, may also make one of them disappear (visually).
Have anyone else experienced this runtime bug? Any suggestion on how to solve it? Again, this issue is just found on a small amount of treeviews and never occurs while running the pbl from Powerbuilder.
