REAL Studio 2010r3
We already have a few bug reports REAL Software said they will fix in a 3.1 update. For example feedback ID 12772 where a project with the line "Backdrop = LogoMBS(500)" in a window.open event in Cocoa will not show the picture. Although the picture is there and you can see it in the debugger or if you display it in a canvas.backdrop.
Please email us about any problem you find related to our plugins so we can fix it.
