Designer freezes when opening a file

[Rik]

APOLOGIES as I've posted this in the Graphics Chat forum already but got no response.
Probably because it was the wrong place!

I've had this problem with XDP6 and now I have it with XDP7 as well.

If I am opining a file (double-click on it to open) and I don't have all the fonts that may have been used in the file, then I get a message telling me so, but, I cannot click on the 'Continue' button to do so.

Designer is simply frozen, no matter how long I wait.
I can click on all sorts of things but nothing happens.

I have to CTRL+ALT+DELETE to shut down Designer.

If I have Designer open already, then sometimes I can click on 'Continue' but not always.

I hope there a solution for this.
