problem editting metadata from version 9.29 and on

[Reader53]

I have a strange problem,

Updated my calibre from 9.26 to 9.34, then when trying to edit de metadata from a book, the edit screen appears but I can not do anything in that screen, the only way out of the edit screen is with the ESC button.

Go back to the 9.26 version everything works OK?
Try to find from which version the problem occurs:
9.26 > 9.27 all works ok
9.27 > 9.28 all works ok
9.28 > 9.29 problem with editing metadata
9.29 > 9.30 problem with editing metadata
9.30 > 9.31 problem with editing metadata
9.31 > 9.32 problem with editing metadata
9.32 > 9.33 problem with editing metadata
9.33 > 9.34 problem with editing metadata

I have tried this with both the x86 an x64 version's, both give the same result's

I am using windows 7 Pro x64 in the dutch language

Anybody who can help?
