huge problem with text to curves

Hello guys...

Ive got an very bad problem when trying to convert text to curves in corel X7 64bit.

Does not matter what kind of text or font... whenever there's a word with color in it and the rest of the text black, convert it to curves and it removes all the color (it makes for instance the red text black).

Tried it with the basic text and the textframes... both the same result.

2 other computer wich i made an fresh install had the same problem!

When publishing to PDF the same happens.

The biggest problem is that all the prepress we make must have text as curves wich has allready gone wrong for 2 times and we needed to order the job again. It costs a los of money and time this way to do the job right.

Do more people have this problem and/or tackled it?
