I must be being dim here, but I can't get the IDE to work.
It's a problem with saving sketches. Basically, once a sketch is modified, I can't save it - I get the message "some files are marked read-only..." (I'm sure they're not). It then goes into a Save-as dialogue box - if I try to "Save-As" and select the original file, I get "you cannot save the sketch into a folder inside itself ..."
What's doing on? It's driving me crazy!
