Very strange problems with text
I'm having a strange problem with a Delphi 5 application that's running on several pc's. The problem occurs mainly on Windows-NT machines (not all), I haven't seen it on Windows 2000 pc's.
Problem is that, when the user highlights some text in a Delphi control, the text color changes in the same color as the highlight color (clNavy). So, no text is visible anymore (text and background are the same). This happens especially in RX Library components.
Also, on the same pc's where this problem occurs, the text in an RxDBGrid behaves very strange. Sometimes it can't be deleted with the backspace key, and sometimes you can type characters over the existing characters, so you'll see the old and new characters in a clutter.
Anyone knows this problem and (more important) a solution?
By the way, what happened to www.rxlib.com (the RX Library web site) ?
Thanks,
JDN

Sounds more like a hardware problem rather than a bug. Could be the video card and the resolution it is set at or the monitor.

Hi,
Find out if the comdlg32.dll and ocx are the same on both machines. the one that it works and the one that it does work. and replaced withthe newer one.
This fix worked for me between win98 and winnt.might work 4 u

Sorry Dean, that didn't solve my problem.
Service pack the NT machines. This is the safest way to guarantee compatability. I am suprised that copying comdlg.dll etc. from win98 works on NT.. let alone didn't complete break it. Definately not a recommended approach.
The rx components in our prods haven't cause any probs on nt workstation for years, so I'd guess the faulty ones haven't been service packed up to date.

I didn't copy the Windows98 comdlg to the NT Workstation, but the comdlg from another NT Workstation (where the problem didn't exists).
On all workstations SP6a has been installed.
I also installed a Microsoft library update for Windows NT. But, until now, the problem persists on some NT Workstations.
It's very annoying. You cannot delete text in a RxDBGrid with the backspace key. And the text in a TDateEdit (also an Rx library component), when highlighted, sometimes gets the same color as the highlighted background (dark blue).
