A bit of a note on dolphin going totally awol as soon as the cursor is moved 
over a canon raw photo file.

Dolphin just disappears basically and a crash report pops up.

I recently added some older canon raw files that are dot crw rather than .cr2. 
CR2 is the one that causes the crashes. dot crw just does nothing and open with 
can be used and it makes no attempt at showing a thumbnail. Cannon and others 
will no doubt continue to change their file naming every now and again each 
time a new camera comes out basically so that they can tell the difference.


Can't help laughing. It reminds me of my 1st excursion into commercial software 
production where I rapidly learned that there is a need to filter out what 
subsequent software will accept and do nothing if not in the list as painful 
and boring as that may be. In my case it was not fully scanning keyboard input 
intended for entry into a data base. The data base accepted what it was given 
as it should as in this case that wasn't it's responsibility. Things are a 
little different when the entries were read later - the odd characters might be 
disc errors and couldn't display so it threw an error. The solution was to scan 
every entry for acceptable characters and wipe the field if there are any 
problems. That discourages users from messing about which some will do.

Duncan might like to note that once I wrote that input routine it cropped up in 
every bit of code I wrote. It makes a lot of sense to only write one function 
and always use it- re akanodi etc. :-) That also encouraged me to move out of 
commercial software development as I prefer a more varied life. This attitude 
also helps me accept change. Things often get in such a mess eventually that 
things have to be re done from scratch and improvements and changes get harder 
and harder to add as the code evolves. The only answer at some point is to 
throw the lot away and start again. :-) My management used to hate that as they 
always do but the problem can be minimized via due attention to structure.
