--- Comment #6 from Bruno Jesus 00cpxxx@gmail.com --- Copy and paste seems to be working fine now in wine 1.9.8. The steps I did were:
1) Open the suggested file by the program yychr98.chr 2) Click in the white color in the first color selector on the right (top one, not the bottom one) 3) Click on the right pane drawing some pixels white pixels over the black 4) Press copy in the toolbar and then select the next pixel block in the left pane 5) Paste (works)
