The re-painting due to mouse-click under MS Windows is caused by line 561
...
of windisp.c. Upon left mouse button up the plot recangle is invalidated,
and a WM_PAINT message is generated (same on line 614 for right mouse
button up). If not re-pained, artifacts may be left on the canvas after
collecting coordinate data.
Shifting the command InvalidateRect to a place where it becomes active
only after the mouse has been moved, does the trick. Simple clicking
(right or left) will not cause a re-paint any more.

Redo the transformation vswitch -> pswitch
...
Parsing takes default values into account, when
parameter is missing.
S vswitch --> pswitch code model
S_ST vswitch (with hysreresis) --> SW switch
S iswitch --> aswitch code model
S_ST iswitch (with hysreresis) --> CSW switch
Use string handling for replacements: allow parameter
equations in .model lines.

Retaining the mixed case of Cider quoted string valued parameters. Limit searches for ic.file to D*, M*, and Q* device instantiation lines. Cider model (numos, numd, nbjt) detection is limited to .model lines. Continuation lines which do contain these tokens are not checked, but this should rarely happen. All of the examples/cider circuits meet these assumptions. Memory errors have been removed.
