Mouse graphics bug

In a recent release of the RISCOS software, there’s a bug which leaves dead pixels or dead blocks of pixels on the screen when the mouse is clicked. I got an immediate response to my inquiry about this – thanks Ben – which included a program to fix the bug. My problem is: How can I get this program into the Pi? I’ve copied it from the email onto the SD card but it’s still in the Windows filing system which RISCOS doesn’t seem able to access. Can anyone help please?

Mmmm current NOOBS downloads has an old ROM version that suffers from your symptoms.
Without more information it is impossible to say what you should be done with the file you’ve been sent.
Telling us the file name might help!

n.b. If it was a zip file. DO NOT unzip it on Windows. Copy it to the Pi and unzip it within RISC OS.

Rereading your post makes me think you may have on a PC copied the file into the FAT partition.
If so, whilst running RISC OS. Hold down shift and double click on $.!Boot you should see in the directory window a file called Loader double click on it it should open up a directory viewer of the FAT partition. Your file should be there.

I seem to remember that after some of the alpha-blending support sprite code was checked in you get corrupted blocks (window furniture and rainbow patterns rather than the non-hardware pointer mouse trails) until you updated your boot sequence to match so might be that if you’ve not pulled a recent HardDisc4 down.
