Not happening on Mac, so likely a Windows build issue.
(There's no 4.0.1 CRAN package yet, and no nightly build of 4.0.1 Patched, but the only thing changed in the sources since r78644 is the VERSION file.)

Hi,
The following code, from the examples in ?TkWidgets , immediately crashes R 4.0.1 for Windows:
--------------------- snip --------------------
library("tcltk")
tt <- tktoplevel()
label.widget <- tklabel(tt, text = "Hello, World!")
button.widget <- tkbutton(tt, text = "Push",
command = function()cat("OW!\n"))
tkpack(label.widget, button.widget) # geometry manager
--------------------- snip --------------------
Session info (prior to the crash):
--------------------- snip --------------------

I observe this behaviour both in the Rgui and when I run R in a terminal. I think the problem is general to the use of the tcltk package.
Best,
John
