Toad version is 9.7.2 on a Vista machine is encountering the issue "Single Record View Doesn't Display Column Names after resizing the window". if I grab the bottom right corner of the single record view, drag it all the way to the top left corner of the window and than back down. All the column names are gone along with the Cancel button.
The issue only appear on a Vista PC, working fine on a XP.
Waiting for fix in a future release of Toad for Oracle
