Teo

I cannot reproduce your problems.

See the files in

http://www.geocities.co.jp/tmgpltwin/Files/Files.html#0065

labels.zip


labels_5.0.png, labels_5.1.png : normal screen setting (tested on 5.0.0 and 5.1.0(cvs))

labels_e_5.0.png, labels_e_5.1.png : font enlarged (150%) screen setting.


I have tested on windows 7 Home Premium 64 bit.

Am I wrong in operation of the control panel?
