I get out of memory exception when using "heavy" components with graphics. I have created library with multimeters / PSUs / connectors and other equipment with some graphics (for better look). After some time of working, adding new components to the schematic sheet I get "out of memory exception" which caused lost of my work (corrupted file have overwriten my work and could not restore). Can you add to ".tmp" file and if succeeded then delete original and rename ".tmp" one?
Thank you to Jaroslaw Sulkowski for contributing a fix for this bug. It will be released in TinyCAD Ver. 2.90 soon...
