I have loaded XP professional on to another partition on the main computer. It runs OK with a dual boot with win98se on the primary partition.

But one problem I have noticed is that loaded images don't appear in the image gadgets all the time. Also I have some code that places text on images. The text appears on the image only very briefly in XP and then disappears.

In win98se no problem, it works fine. Is there something I need to do or watch for when running under Windows XP?

I thought it might be something to do where I place the jpeg encoder/decoder plugins but apparently not.

ie UseJPEGImageDecoder()

Hi, exactly the same (xpprof and win98) and in some cases my code crashes ;no debuggermessage; the debugger closes too.

If I want to load a JPEGImage into an ImageButton, the Visualdesigner crashes, do you have the same Problem??(VD version 3.8 )

Can you post some code that shows the problem?

Posted: **Sun Jan 04, 2004 7:04 pm**

Mitch, here the code that is causing the problem. I have cut a lot out but hopefully there is enough to show you. It probably wont run as it is.

YES :roll:

You seem to use a very old version.
The new version is @ http://www.purebasic.be/download.htm
Don't forget to mention the build number in your posts, else it's for me impossible to check things.

I tested the 3 lastest releases, none of them chrash when loading a jpg.
Please try with the latest build, if still fails, mail me the project file.
If Fred finishes the upload script, Visual designer updates will be possible using the AutoUpdate tool.

Good news

Posted: **Wed Jan 07, 2004 7:36 pm**

Incidentally, I checked to see if I had directX loaded. Yes I have. So it is not that that is causing it to not work in XP.

Any ideas anyone ?

Okay... i finaly found this bug.
New version online.
And .... 'Lazy Fred' did not yet finished the upload script, so you can't get the bugfix with the updatetool
