RHEL6 Bindkey problem in schematic editor

Hello,

We have just began with updating the machines to RHEL6 and covered a problem with a bindkey in the schematic editor!

As standard, Shift + 9 is set as the default bindkey for removing the probes in the schematic, but this bindkey is not working anymore with cadence 616 and RHEL6! If i change it eg to SHIFT + 8, it is working again!

Can anybody help me or knows this problem?

Thanks in advance, BR

Franz
