Processing... Please Wait

[Thev]

I am having an issue with a few of my older Xara graphics files. Selecting any objects (incl text) on these 'broken' files causes a significant delay in processing (curser changes to: Pointer (then) HourGlass (then) pointer - repeat many times), and a notification in the lower left side of screen "Processing... Please wait". This pause or delay happen on each mouse click. It renders the files fairly useless.

The real PITA is any objects copied from this file and placed on another "clean" file to facilitate editing, brings the 'Processing' error along with it.

This is a fairly old file, probably originally made with Zara v9 or something of similar age (been using Xara since ~2006); however, I have other old files where this is happening as well and they were all made with different versions of Xara. It's not common to one version.

I attached a screen shot - video to demonstrate it, hopefully it'll upload.

Any Help is appreciated as I would like to regain functionality of these broken files and learn how to repair files when this happens again.
Thank you,
