Show Structure Builder not working, sometimes

[saidelike]

I have noticed sometimes (not sure why) when I run IDA and load and an IDB, I can't start the Structure Builder as it does not appear with the RIGHT CLICK menu and also the ALT+F8 hotkey does not work.

A workaround is to just close this IDA instance (closing and reopening the IDB in the same IDA does not solve the issue), and reload it. It usually then works fine.

It may be due to the plugin not loading properly?

It was tested with the latest IDA 7.5 SP1 but it used to do that with older IDA too.
