Hi, Running the following test with the latest context (MK-IV 2010.05.13 12:15) gives the following error. Compiled fine with version MK-IV 2010.04.29 22:30 (side note : integral symbols still not displaying correctly) I was just wondering, is there a ConText test suite which I can use to test the stability of a version ? It is difficult to determine between versions, what is working. I have some small test files myself, but they only serve as a minimal test to see if I can at least run them without getting errors. !
