OS: Windows - 32 bit
In "Change timestamp" dialog, when opening the dialog or toggling "Create EXIF data if needed" checkbox, the layout of the dialog changes slightly (some few pixels). See screen recording topic_35086_helmut.wmv.
Effect: Small UI glitch (minor/cosmetic issue)
To reproduce:
1. In XnView browser select an image file
2. Select Tools » Change timestamp
3. Check/uncheck "Create EXIF data if needed" checkbox
Actual behaviour (bug): Layout of the dialog and the preview changes slightly

Expected behaviour: Layout of the dialog and preview should remain unchanged.
