A Main Window pops up with "Main Window" in the Menu bar. Click on "Main
Window" and the first (and only) item on the menu drops down and it is
called "Normalize". Clicking this opens another windows entitled "Get
Method". If there is a problem (it is intermittent), it is evidenced by
the fact that the "Get Method" window will not close.
It cannot be closed by clicking. The window is frozen open. It can be
moved but not closed. On MS Windows, the "Get Method" window can be
closed using the right button close window option on the task bar icon
Typically the problem occurs infrequently in the first 10 presses on the
"Normalize" item, but more frequently there after.
I have NOT had the problem on Mac OSX or Linux.
On MS Windows (I have tested on Win XP-32bit and Win7-64bit) the problem
occurs in R-2.16.0, R-2.15.2, R-2.15.1,R-2.14.0.
THERE IS NO PROBLEM WITH R-2.13.1 and R-2.13.0
I have run it using debug("GetNMethod"). Stepping through the GetNMethod
function results in freezing when asked to do the "tkgrab.set(GNMethod)"
instruction.
I would appreciate if others can confirm similar behaviour.b
Can anyone suggest why it worked under R-2.13.x but not in later
versions of R.
Was there a change in R that impacts with this aspect of tcltk?
Is there a work around for this problem?
If all you are interested in is closing the Window, it seems on my
Windows 7 system that right clicking the corresponding button in the
task bar at the bottom of the screen to bring up the local menu, and
choosing "close", will successfully close it.
Of course, this doesn't address the real problem.
