#51917 Make your graphics area just a big bigger. Add about 20 pixels in x and y.

The browser automatically adds a bit of padding. This is inconstant across browsers so I suggest making the graphics area just a bit bigger than you need.

#51933 aha so basic needs padding to cooperate with the browsers so this is why 589 is too close to the 600 mark so if you need 589 you may want to use 611 rather than 600 for instance.

Interesting I'll have to keep mind as one of the quirks of working things.

Along with the gosub without a return more than 250 times causes a crash.

These are operational things that somehow need to be documented or remembered there are these subtle quirks very important to know these things. Thanks for sharing.
