Hi.

Had time to test it out today:

Setting component values works well now.
Pausing sim. works (but no text hint in the main window as the old ver. had) 
Deleting works

Gfx error on e.g. LED in that I can't connect a wire unless I rotate the part. 
Som gfx errors that leaves gaps at connection points on components.
(see last email with attached screen shot)

That's all I had time for. I will test more after my holiday. Keep up the good work :)

Regards,

/C
