[Bug,VW7.4] Debugger Run To Caret Problems et. al.

DebugIt in a workspace:

#(a b c) do: [:each | ].

Step into the block, then place the caret after the block (or in the next line)
and press "run to caret". The debugger UI deadlocks.

Has anybody by chance got a fix for this?

If the caret is placed inside the block and "run to caret" is chosen, an
exception pops up [*]. I recall that a similar bug was reported earlier ("vw74
debugger Run to caret gives walkback"). Maybe the same fix applies to both
problems?

Another minor bug arises when setting conditional probes:

In case the probe condition expression refers to an undefined variable and
"correct spelling" is chosen in the dialog, the source string is not modified
to reflect the corrected variable name. Anyway, the compiled code seems to be
correct.

Currently, this is an undocumented restriction in the debugger.
The basic issue is that a probe cannot be inserted into a
doIt method. In the case of run-to-caret when you do a run
to caret and the caret is not in the same block as the
selected context it inserts a probe.

I guess we either need to figure out how to insert probes in
doIt methods or disable the features in the debugger that
insert probes when debugging a doIt method.
