I have found some problems using tpt++,they are-

1) The menu in which we see our saves (which are saved on hard-disk and not in stamps folder) i.e in ".cps" fomat we are not able to delete them in the game and cant scroll the pages in it.HINT: To open it press CTRL+the icon we used to see the saves on net.

2) The new element tungsten glows at a very high temperature so it is difficult to provide that much heat to it using other elements
(well it can be provided but still it will be good if its glowing temp be made less for e.g. at 500 degree or else it make more heat when sparked i.e 300 at the place of 59.00.

3)when we open the stamps i.e when we are just about to paste a stamp the preview of 2 or more stamps get mixed and when we paste it it disappears why?

4)A new bug found when we are just about to paste a stamp press any key and the arrows keys the pixels "get moved" this should not happen because i remember it was ctrl and arrow keys not any key and arrow keys.

That large scroll area even does not works we can just open the saves which are displayed not all the saves.And see the 4th bug above I found it just now.
