Embedded colour profile!

It appears that my Coreldraw X5 files are randomly 'embedding colour profiles' when saving!

As default I have this function turned off but random files appear with the colour profile embedded.

This causes a problem on other machines in the office who have to import these files, Coreldraw just hangs in these instances and crashes saying 'not responding'.

Does anyone out there experience similar problems or have any solutions please?

Many thanks in advance
