Shalom and greetings all my pals,

I finished successful installation of Captain Sims 707 and 707C into FSX Deluxe with SP1 and SP2 set in Windows 10 Pro.  Everything seems to be working during ground testing except what is said on the subject heading

I noticed lighted overheat warning on cockpit windows so I clicked the window heat switch button in order to turn off heat but the switch button went from high through off to low. So I tried to click again in order to make the switch go to off position to turn off heat.

Unfortunately the switch refused to from low heat position to off position.

What can I do to fix this problem or shall I ignore window overheat warning?

Regards,

Aharon
