Amaya 8-7pre WinXP bug: empty parsing errors window

Hi,

"File > Show parsing errors" menu option works in the html window, 
but does not work properly in the css window (in Amaya 8.7-pre for 
Windows XP)

Steps to reproduce error:
1. Create a new html document
2. Link a new css file
3. Open the css file and edit a wrong css rule, for example:
    p { color: blac; }
4. Save and reload the css file. Select "Edit > Show parsing errors". The
window is empty.
5. Reload the html file. Select "Edit > Show parsing errors". The window
shows the error:
    line 1: Invalid color value "blac"

Best regards,
Barto
