I said the following in my last post..
In Aircraft Manager/Weight balance there are the variables, fuel, pilot etc and a + and – box adjacent. I take it that this is for modifying the lever arms. When trying to increase the value I got an error message “Unhandled exception has occurred” etc and ending in (Object reference not set to an instance of an object). If I now press the Continue button the error message disappears, but if I hit the Quit button the entire SkyAngel program closes down.
Conversely, if I want to decrease the values by pressing the (-) button, the whole line, (name and lever arm) disappears.
This is a problem caused by my laptop not your software so I'm sorry about that. I've loaded it onto my PC now and everything is OK.
I think that the weight balance should be in LBS and Inches. I've always calculated in these and I've always thought it was the most common way of doing it.
