One big issue for me in Windows 7 after XP is that text in browser windows (like in IE9, Firefox and Thunderbird) lacks contrast - it's a pale grey rather than the black I had in the same apps in XP. Actually this text is pale grey as I type it.
This seems to be "global" and no amount of fiddling in the apps themselves does any good. There was never any problem in XP.
I'm using an Aero theme, but I've tried a basic theme and tried chaning the window colours manually, but I can't solve the problem (and I rather like Aero anyway!)
At my age I'm really finding this a problem - how do I solve it?
