OS: Windows XP - 32 bit
When opening the IPTC/IIM dialog and closing it using "Cancel" button, it takes a short moment (<1second) to close the dialog but it sounds as if there are many (hard) disk accesses.
Effect: A bit irritating (minor)
To reproduce:
1. In XnView browser, select an JPG image file.
2. Press Ctrl+I to open the IPTC/IIM dialog
3. Select "Cancel" to close the IPTC/IIM dialog
Actual behaviour (bug): The dialog closes and there are many hard disks accesses when closing.

Expected behaviour: When canceling the IPTC/IIM dialog, the dialog should close without any hard disk accesses because nothing has changed.
