Problem with custom palette

[Adda Macchich]

At work we use CorelDraw and PhotoPaint. Someone had created a custom
colour palette with the 'house' colours and saved it somewhere on the
network ('P:\' drive). This palette was subsequently deleted from this
location and I recreated it and e-mailed it to everyone in the department so
they could have it on their local (C:\) drives, under the Corel custom
folder. This works better as the network is huge. The palette can now be
selected by going to view->colour palette and choosing "custom colours".
However, there's still a pointer somewhere in Corel's configuration files to
the old palette, which produces an error message on both Draw and PhotoPaint
upon loading and exiting the programs, that goes like "Error, file
P:\masters\DMG.CPL not found". Somehow I manage to get rid of it on a
couple of PCs but this was about two months ago and now I can't figure out
where to clear the reference to this non-existent file as there's nothing
under 'Options'. Recreating the file is not an option as the P:\ drive is
read-only.

Any ideas welcome, preferably by e-mail to amac...@netcomuk.co.uk
