Hi Agep!
Ooops, that's exactly the same (timing) problem that I had yesterday also with all other modules, but I've fixed this for these modules.
Now I just see that the Glasgow uses own routines in 'glasgow.c', so I guess I'll have to try finding a fix also in this source file.

Until this problem is solved you just need to click with the mouse on the destination field (with the piece that is captured) a bit longer, i.e. don't make a very quick click, but hold the mouse button a bit longer (even 1/2 second is enough) - then the move is correctly registered and everything works as for all other modules.

Thanks for the info,
Franz
