Since reporting I have found this problem does not always arise, so am not
surprised that others have not reproduced it as with a total of two or three
windows open it does not seem to occur. It does occur when there are
several windows open, but I have not been able to identify a set of
sufficient conditions. It initially occurred when running project manager
with several script windows open.
The error message is
Error in jijs_tile_button
index error pmovex
wd 'pmovex', ". .....
