Is the box ticked or filled? If it's filled, it means that there might be some read-only files in the folder.
Box is filled.
By clicking I cycle ->clear->ticked->filled->clear->...
I clear it & ok
then do properties again
and it is again filled
Now I create a new (hence empty) folder (I've checked ls -la from linuxhost. There's no hidden file being created inside the new folder) ...and do the same process, right-clicking on this folder -> properties -> ....
it re-fills the box each time
Creating a new file, the file behaves ok. It's just folders that play up.
As for Visual Studio, there is a known limitation of the SF. Compilers can't build on it. This is with every compiler, Windows, Linux, you name it.
It may be that the compiler refuses to attempt to write to a read-only folder.
Would this approach fail even without this read-only complication?
If it's a definite nono, I'll have to find some other way. Do you know why this is the case?
