--- Operating System, Graphics card ---
Win 7
ATI HD 4600

--- Blender version with error, and version that worked ---
2.65a (Error)
Do not have other version installed to test if it works

--- Short description of error ---
Blender crashes when entering large value in Subsurf Modifier's View field.


--- Steps for others to reproduce the error (preferably based on attached .blend file) ---

1) Open default blend file with cube
2) Go to Modifiers tab
3) Add modifier
4) Subdivision Surface (under Generate column)
5) Click centre of "View" under "Subdivisions:" label to input custom value
6) Enter large value (e.g. 100) and Blender crashes. Please note that max allowed value using increment buttons is 6, so this is probably a low priority bug

Cheers!
