I'm having problems with completion if I type too fast. This is an old problem that has come back in 1559.
For example, when typing "StreamWriter sw = new ", I have to pause after typing the last "w", before I hit the space bar, or VAX will not offer me a completion box.
Fast (and I'm really not that fast) typing also leads to variables being converted into what seem to be totally random names from who knows where. Again, an old problem.
I am seeing this also. The odd conversions happens with if statements a lot. I 'll be typing along and when I get to the end of the variable the whole if statement is replaced with just the variable.
