Hello,

Used:
Ubuntu 14.04 on a Laptop with deleted Amazone-Files
Wine 1.4, 1.6, 1.7
Nvidia Grafiks

I've tried to log into my Steam-Account with Wine 1.7 (works with all version's) after fixing the 'No Text Problem' (disable dwrite.dll).
The Text-Box for User-Name and Password doesn't work. You CAN click into the Text-Box but you CAN'T type in your User-Name/Passord.

I've fixed it...

1. Open winecfg
2. Add Steam (If you haven't even done this)
3. Choose Windows XP or Windows 7 for Steam.
4. Click OK and have Fun
