I recently reformatted my hard drive and reinstalled the free to use version of CS2 on my PC. I'm running 32 Bit Windows 7. Since the install Photoshop will not allow me to use Shift+ Cursor to resize with constrained proportions. When I press Shift the cursor freezes and I am unable to move it no matter how hard I press on the track pad. If I resize and then press shift the image will square out. It appears that only the scroll function is disabled.
I know from reading other forums that proportion constraint can get buggy with other applications and extensions, including certain web browsers. Knowing this I shut down Photoshop and all other programs and applications and then re-started it. It did not fix the problem.
Any help with this matter would be greatly appreciated.
