Hi Polya
Thanks for your sample project, while i wasn't able to run it, after you said that this should also work, i've tried creating a new project and can indeed see that confirm windows can also have scroll viewers.
Unfortunately, the project that i'm working on is too big for me to just snip out the relevant parts needed to replicate the issue.
Could this have something to do with another issue i had (raised a support ticket with ID threadid=983814) to do with the type of binaries i'm using?
