Two of my colleagues and I are experiencing issues with TOAD reducing our column sizes where it doesn't size to the header or the data (sizes to 1 or 2 characters of the header). It happens when we run execute/compile (F9) the first time, but when we run execute/compile again, it sizes to the data correctly as we have it set in our settings (View --> Toad Options --> Data Grid --> Visual under "Column Sizing" has the selection "Size to Data"). While this happens frequently throughout the day, we notice that it happens randomly. Sometimes it doesn't do this, but most of the time it does.
