Using Windows 7 Ultimate

When running the rescannewgrf command twice in quick succession, a game crash occurs.

To Reproduce: (Works best when the game has a lot of GRFs to scan.)
Run the rescannewgrf command twice in quick succession.

Suggested Fix: When attempting to run the rescannewgrf command while the newgrfs are already being scanned, it should, instead of restarting the scan and crashing, output "Error: Newgrfs still being scanned, please wait til it's finished.", "ERR_NEWGRF_ALREADY_BEING_SCANNED", "ERR_NEWGRF_SCAN_IN_PROGRESS" or something like that.

"Run the rescannewgrf command twice in quick succession" - how are you doing this? Seems impossible from the in-game console thus I see no need for a full-blown, language-aware GUI error. It's rather a case of blocking/queuing/dropping calls to rescannewgrf properly. The in-game console (~) is already blocked when scan is in progress. It should be anyway - is it different at your side?

I meant: Type 'rescannewgrf', then press the following in quick succession: Enter, Up arrow, Enter, Up arrow, Enter, ...

What version of OpenTTD are you using? Where did you get it?

I meant to say OpenTTD 1.7.1, downloaded from the Openttd website.

OK I see where's the problem now. At lest one of them. When newgrfrescan is in progress, hidden windows receive and process keyboard input (they shouldn't). So it is actually possible to run the command twice, even though you don't see it. It's a separate issue how commands are processed inside scripts tho.
