This report is related to the bug `'tcltk' crashes related to
event-loops' PR#14187 [1]. The difference to that bug is an inversion
of the command sequence.

With the following sequence I get sporadic freezes of tcltk.
require(cairoDevice)
require(tcltk)
Unlike for the previous bug, I am unable to identify a simple and
reproducible sequence of commands. To avoid the crashes documented in
PR#14187 and to able to use playwith and Rcmdr in the same R session,
I have been starting the two in the following order:
require(playwith)
require(Rcmdr)
Generally after some time of working with both (say, 30 min - 1 h),
tcltk freezes (the Rcmdr interface is still there, and I can click on
"File", for example, but the menu shown will be blank). Closing Rcmdr
I get the following error message:
Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"),
class = "tclObj") :
[tcl] invalid command name "get".
After the first freeze occurs, anything tcltk does not work (for
example, restarting Rcmdr will display a blank window, just as a
relimp::showData(iris) command). Unfortunately, I cannot isolate
specific actions that trigger the freeze.
