this morning i was having terrible trouble with crashes to JT65-HF when using JT-Alert......i was also getting a problem with my screen going black from the top down to about halfway...think thats a local problem.
decided to set JT-Alert to independent of JT65-hf in the JT-Alert menu instead of docked to the bottom....must use some type of hook (fish hook ;-) )
since i have done that X fingers no crashes when moving the mouse within JT65-HF....
will continue to trial this and will let you know if i do get any crashing
remember im using Ubuntu 11.10 with Gnome Classic desktop and JT65-hf and JT-Alert under Wine
