I forgot to add this: when I look at the DOSBox process in the Task Manager window, it appears to be using zero CPU.

Cheers,
Dave.

that is indeed very odd.
the slow speed combined with zero cpu usage is a bit odd.
Which version of DirectX do you have installed ?

9.0c (4.09.0000.0904)

did you try changing the output mode?

Yes, that fixed it.

But this is strange...

I changed it to 'overlay' first and I couldn't get anything to display at all. Next, I changed it to 'opengl' and when I loaded it, my PC hung for around 15-20 seconds. But it did show the DOSbox window properly and everything was behaving fine.

I've now changed it back to 'surface' and it is now behaving perfectly. Even after rebooting everything is working fine.

So... uhhh, I don't know how to explain it but it's working great now. Thanks for the tip.

Dave.

Just to add, I think I know what caused this problem.

Has anyone reported any problems using DOSBox and running Java at the same time? I've realised the DOSBox has this error when I'm running Azureus (a Java BitTorrent client). I also tried running a different Java program and then tried running DOSBox and the same problem happened again. If you quit these programs and restart DOSBox everything is fine.

Just thought you might want to know.

Thanks again,
Dave.

Hmmm, reminds me of problem I've noticed on my system. If VirtualPC console is running DOSBox gets really slow. But that affected only opengl renderer. Just like in your case, it does not make much sense -- that console is very lightweight launcher app with minimal graphics capabilities. Our systems have some common items but the video is totally different.

Hello! I'm having exactly the same problem but I don't have any Java application running.... I can change output tu anything, it still doesn't work, except OpenGL, which makes the thing work after 30 seconds, but only if I don't switch the windows (problem is that I'm always doing 2 things at the same time ^^). Any idea? ^^
