If I have a .mrc file i.e test.mrc and I try and load it from within the script editor it won't work, unless I manually append .mrc in the windows explorer window that opens.
Steps to replicate:
1. Create a .mrc file in the folder that mIRC keeps your scripts.
2. Press alt + r to open the script editor
3. Click on file and select load
4. Navigate to the .mrc file and click open
One cannot open the file. I used to be able to open the file on previous versions without any problem.
I am using windows 7 and the latest version of mIRC.
