Malfunction in apps built on Max 6
Hi there,
Apps built on Max 6 fail to display the UI components as well as function as it should, which I guess unsurely might be because of the compatible issue between the new Mac OS and the apps built in the old 32-bit environment. I don't have the source codes so can't built them again on Max 7 or 8.
Does anyone have any ideas about it or how to get around? Many thanks!

if the runtime would be incompatible with your OS you wouldnt even see a broken patcher window i guess. :)
Try this :
right - click or control - click on that Standalone app, select "show package contents"
and navigate to Contents/MacOS/ and doubleclick executable file
to start it via Terminal.
It should give You some info about what is being loaded, missing etc
I had similar problems in the past that were solved after installing the old Java6 available on Apple's website.
Many thanks to all of you!
Yet I am not able to make it after installing the old Java 6. Meanwhile I've found another post about this issue in the forum:

I'll try out the solution suggested there later.
