RE: [Vnc2swf-users] memory error using localhost

[Bill S. <bil...@ly...>]

Many thanks for the reply.  No worries on the delay, the tool is worth
the short wait!

The memory problem does seem to be confined to my laptop.  The unusual
feature of my laptop is the screen resolution.  At 1900x1440 it is
larger than most?  Only thinking to try now, I've not been able to get
the VNC viewer to view my machine from another either, though viewing my
own machine - what a screen mess - works OK.

Regards

Bill

Well, I've heard some people still get MemoryError even after they
turned on the local connection. I know that MemoryError occurs
when it tries to read negative length of data from sockets. So
still something gets wrong here...  But so far I couldn't replay
this error on my environment.  As you said, I don't think the
actual memory size is a problem.  I'm still trying to figure this
out, so if you find it works on some other machines and discover
some difference, please let me know.

Oh, sorry, I just noticed there's a silly bug. Problem 2) and 3)
should be fixed with the following patch. I'll release the fixed
version as soon as possible. Thanks for reporting.
