Windows 7: Color dialog prevents third digit in RGB text boxes ?

12 Feb 2010   #1

Color dialog prevents third digit in RGB text boxes ?


Running windows 7 Pro 64bit.
GUI - classic theme, 108 dpi.

I was allways using some solid custom color for my background. So I tried to select it using Personalize.... custom color dialog. It's standard color dialog present on all windows versions. One of the ways to enter exact color is 3 text boxes(Red Green Blue) with value ranges 0-255. If I try to enter third digit it beeps and input is denied - similar bahaviour if I would try to enter out of range value like 256. But it denies whatever third digit ! It's imposible to enter 100 and so on ! This behaviuor is common to all apps using color dialog - not only background change.

Is this a bug ?
How do I resolve this ?

It's not a bug, because if I under the method that you used, I can adjust or enter any numbers that I want:

I believe issue shows only on certain circumstances - can you confirm that your color dialog works ok using classic theme and 108 dpi ?

Have absolutely same problem.
Running windows 7 Ultimate 64bit, GUI - classic theme.

Problem revealed after maybe half year of using Win 7, after fresh installation everything was okay. But now cannot change colors in no any other application - the third digit cannot be entered
