|Summary||0007415: RFB Client: 'doesNotUnderstand' exception while entering password when trying to connect to local VNC desktop.|
This happens about 4 times out of 5 attempts -- it will connect successfully occasionally.
Actually, this exception is 'handled' (i.e., logged and then execution continues), I only noticed this error via the Transcript, and then inserted a 'self break' in 'RFBClientSocket runSafely:' so I could debug. Regardless, this causes the connection attempt to 'silently' fail, if one doesn't have a Transcript open, one might be completely clueless.
This appears to be Morphic-related. Looking at the stack trace, what seems to be happening is that during RFBCLient>>rfbAuthentication a FIllIntheBlank morph is displayed. This morph has a loop to allow events to happen while the user types the password.
During this loop, HandMorph>>noticeMouseOver events are reported, and eventually 'leftMorphs' is nil:
MouseOverHandler>>noticeMouseOver: aMorph event: anEvent
"Remember that the mouse is currently over some morph"
(leftMorphs includes: aMorph)
ifTrue:[leftMorphs remove: aMorph]
ifFalse:[enteredMorphs nextPut: aMorph].
overMorphs nextPut: aMorph.
(To me this makes sense -- the mouse hasn't left a morph. Oh well.)

|P.S. 'enteredMorphs', and more worryingly, 'overMorphs' are also nil. Hooboy.|

|It would be useful if you could prove the version of your image, vm and rfb package and some information about the server you are connecting to.|

Ooops. Of course.
