In the attached project there is a single form app with a property grid that is linked to an instance of a test class. The test class contains several properties, 2 of which have long attribute descriptions, Value1 and Value2. After the form has loaded, if I select each property in the property grid consecutively, eventually the app will hang. This appears to happen when Value1 or Value2 have been selected after a different property with a smaller description.
However, if the description box in the property grid is resized slightly bigger and the same selection process is done, the app will not hang. Resizing the description box in the property grid will cause the scroll bars to no longer appear in the description box which is the only obvious difference in the UI.
Also, if I shorten the descriptions in Value1 and Value2 to around 50 chars, then it all seems to work ok.
This problem appears in Chrome, FireFox and IE.
