This happened once before but went away after re-installing. [1]. I'm having the same issue again. Basically the behaviour of text selection is changes while I open and edit different files running a single instance of DrRacket. If I select some text and then press SHIFT+Left instead of altering the selection based on the current cursor position, the selection is extended left from the beginning of the text currently selected. Similarly for SHIFT+Right - it extends the text selection one character to the right from the end of the selection rather than the current cursor position. Same for SHIFT+Down, SHIFT+Up. Is there some key binding or setting in DrRacket that controls the way text selection is handled that I am accidentally hitting? It doesn't happen in any other editor - it's specific to DrRacket. If I quit DrRacket and re-open it normal operation continues for a while again. I don't know if it's a bug or some setting in DrRacket that I am unaware of. My current specs are: Arch Linux 64 bit: Linux 3.10.10-1-ARCH #1 SMP PREEMPT x86_64 GNU/Linux DrRacket 5.3.6. (This is a version I compiled myself - but it's the same using the Arch binary package - racket 5.3.6-1) Can someone offer any advice?
