I have 2 Vista boxes I run Workrave on. One of them, 1.9.0 works great (save the occasional invisible break window). However, on the other I receive this error:

GLib-ERROR **: This version of GLib requires NT-based Windows.
aborting...

I've removed it, wiped the directory, reinstalled, looked for other glib DLLs that might be floating around. I'm at a loss as to why this is happening, I can't duplicate it on my other machine, and it's non-sensical. Any ideas?

You could download dependencywalker (http://www.dependencywalker.com/) and check what libraries are loaded on both computers. I also suspect dll loading problems.

As far as I can see. gtk just calls the Windows GetVersion function to check the windows version.

Scott,

Was this issue ever solved and if so can you please tell us what you suspect as the cause.

Thanks,

Ray

It was not. Dependencywalker didn't come up with anything unexpected. I suspect it's an edge case specific to that machines configuration. It's used for dev, administration, and testing, so I suspect it has an unusual mix of software that has been on and off it. Unless someone else reports it, I don't think it's worth tracking down.

Scott, My guess would be multiple gtk libs in the path. Workrave.exe must be run from the \lib directory. Every program dependent on GTK almost always comes with its own batch of GTK libs.
Any bug report usually represents not just the reporter but other people who didn't report. Most people who see something like that just uninstall. So in that sense it's worth pursuing. For now however I'm closing this. Thanks for your reply.

For what it's worth, only system libs and libs from the workrave install were being used, according to dependencywalker.

While the machine is being retired, I think I'll image it to run in a VM. Maybe I'll get the itch to track this down when I have more time.

OK, I finally figured out what was going on. Back when I was running the Vista beta, I had set some application compatibility rules with the "Compatibility Administrator" tool. One of the rules I set was to run workrave in win95 compatibility mode. I had long since forgotten about this, but was reminded when going through a debug session and saw dll's from AppPatch loading...

I removed those compatibility rules and now workrave works again.

So, shockingly enough, running in Win95 mode causes issues with libs that expect NT dlls.

Another mystery solved. Thanks for the feedback!
