Today had Laserweb4 go ferral for some unknown reason.
I am using windows 7 professional 64 bit Dell version.
It locked up will actually controlling the laser. the job finished and I ended up with a white blank screen. Could not close using the x at the top of the screen, could only minimize it. only way to stop the program was to use task manager.
On trying to start program all I got was the blank white screen.
Un-installed LW4 and re-installed but all i got was the blank white screen.
Ended up deleting the folder in C:\Users\tony\AppData\Roaming\lw.comm-server. then reloaded LW4 and all came back working.
Now is ok except I lost some of my settings
