I don't know if anyone submitted this bug already, but with Sharp Develop 2 and using VB.Net I experienced some times that if there is a syntax error in my source code and I try to switch to the forms designer then the forms designer crashes. When I correct the syntax, the forms designer works again. It also looks like sometimes the non visual controls dissappear and re-appear again. I am referring to using e.g. the connection, dataset, data adapter etc. controls. It also looks like some times the forms designer throws away a list view control.
