I've created a program for a customer of mine, but found out something strange.

For this project I've decided to make a UDF (I've got to carry out 8 time's the same sequence) with some timers, ands, or's etc. and also of course I make use of some markers. 5 time's in each UDF.

But it seems that the software also assigns the special markers just as it come's. So it just turned out, that in some case the screen would get a different colour.

The work around is quite easy, by just placing all the special markers first, and the placing the UDF's and build the rest of the program. But this can be quite annoying.
