"Add Expression Evaluator" happens to fail adding variables to the debugger watch list.

Adding variables to the debugger watch list via "Add Expression Evaluator" is buggy
as it happens quite often that the added variables don't even show up in the watch list.

Moreover, each variable in the watch list is associated to a specific "item/frame" of
the call stack. When switching through different call stack frames, at times some variables
which should actually be "visible" with respect to the current call stack frame,
can not be expanded. The triangle in charge with expanding a data type is just missing.

It is very appreciated if these annoying bugs could be fixed as soon as possible.

Kind regards,
