Question: How do i avoid getting matrices converted to rtables after i run my worksheet more than once

I'm currently using maple for calculations of robot kinematics.

My problem is that if i run my worksheet twice  Maple stops showing my results and starts to show e.g. _rtable 18446744074374081822 instead. How can i avoid this behaviour?

(I have a restart command in the beginning of my worksheet)



It seems that the strange behaviour doesent always happen when i run the worksheet twice.

Sometimes i need to run it three times or sometimes i just have to wait for a period of time and run it again. Restarting maple (Closing and reopening the program) fixes the problem every time.

I dont change any parameters between runs.
