Fix to VisualTips from Skybound
Smart PropertyGrid.Net does not use the VisualTips product directly, but the demo sample does. Lately, it was reported an issue (random crashes) with VisualTips if the client application targets .Net 4.0. The solution has now been found and Skybound has published a fix. You will find it here. I remind you that this is an excellent product and it's free.
And since we are talking about tooltips, I would like to outline that the latest SPG build contains refactored code for default tooltips. They now position and size perfectly in various conditions and will also now display well under Windows 7 themes.
