When attempting to fix a function from file that cannot be fixed, Ride generates two msgboxes, whereas the IDE generates one.

[dyaandys]

   (⊂' res←foo arg' 'res←''foo'' arg')⎕NPUT'/tmp/foo.aplf' 1
   2 ⎕FIX 'file:///tmp/foo.aplf'
   )ed foo

Append a ";" to foo[0]
Hit EP .. get a msgbox: "Can't fix"
hit OK .. get a msgbox: "Cannot save changes"

But in IDE only get the "Can't fix" msgbox.

Ride log has
283555 recv ["OptionsDialog",{"token":1242,"type":4,"options":["OK"],"title":"182U64 8808 CLEAR WS:","text":"Can't Fix","questionkey":"Can't Fix"}]
291086 send ["ReplyOptionsDialog",{"index":0,"token":1242}]
291109 recv ["ReplySaveChanges",{"win":1,"err":1}]

This is also mantis 18407 .. although I think this is a problem in the Ride client.
