Microstation V8 2004 edition on a Windows 7 Professional (service pack 1) on a 64 bit OS
I work with Microstation 2004 daily and have been dealing with this issue for about 5 years. I am sick of looking everywhere and finding nothing written about this.
The delete key stops working halfway through EVERY session. I shut down Microstation and restart, it comes back. I resort to the delete icon about halfway through the day after getting tired of restarting Microstation.
