[TxMt] Re: error messages - R-Bundle

[Martin Batholdy]

Dear Hans,

Now it happened to me, that a script was actually finished, but the loading-circle of the textmate-window still indicated, that the script is running.
(I saw that it actually was finished by the files it generates).

I also didn't get any print-messages that were in the code.


best,
martin
