 Last night I opened Esrael Sonic Editor to make new layouts for S3K. I opened the ROM and went to the level editor, and it prompted asking for a savestate. Then I realized I had chosen to read levels from savestate, so I changed it to &quot;Automatic E.S.E.&quot;. I re-opened the ROM and the level editor and got an &quot;Invalid Filename&quot; warning. After managing to open the level I went to the layout editor and got this weird message:&quot;Canvas does not allow drawing&quot;. After pressing accept, another prompted, then another. And then I got a &quot;Par?metro Inv?lido&quot; (Invalid Paramter) windows warning, followed by an acces violation in module eseii.exe.<br>After closing eseii.exe, I had memory problems in windows. The memory seemed insufficent to open a folder, not even enough to use the &quot;show desktop&quot; button. So I opened my antivirus software and performed a complete compuer scan. Of course, by then I had moved the E.S.E. folder to the recycling bin. After some time of virus scanning, the memory appeared to return to normal. I still don&#39;t know what caused this mysterious bug, and in this very moment I&#39;m scanning my computer for viruses. If anyone knows just what happended, I would appreciate it.
