I am using latest FinalBuilder 8.5.0.3497.

GUI version works fine but problem is FCMD.exe.

I don’t know when this started as we don’t used it for a while.  
All builds is now manually started.

The problem is that even an extremly simple script just pause and do nothing as it waits on something.

I made this test project

And try running it from commandline

It just waits forever.  
Then I realise that it pause only if -cf or -co commandline parameters was used.

I could not reproduce the problem here. I had a look at the code, it uses SendMessageTimeout to send a HWND\_BROADCAST with a timeout of 5 seconds.

The information box you are seeing comes from the -le option (log all exceptions) - that actually showed that we have some missing resources (which caused the exceptions) - whch made me realise those resources shouldn’t even be loading at all when running fbcmd - I just checked in a fix for that (improves fbcmd startup time a bit).

have a look in %TEMP% there should be an exceptions.txt - send that to support @ [finalbuilder.com](http://finalbuilder.com) and I’ll take a look.

Build is working fine for me now without those parameters. So for me not an issue anymore
