This is Random as 1/10 time i load the project i might get one desing time to laod perfectly
thanks Mr depressed :¬(
Update I have left this here as it may help someone else
I Now belive this was due to leaving the 7.3 version installed at the same time as 8.1 and all the gac'yness that implies
I removed 7.3 8.1 and reinstalled 8.1 alone and It appears stable
this issue can also arise when installing hotfixes as i found out when i was installaing the hotfix for 9.1. After the install of the hotix I found out (for some unknown reason) that my base form project was pointing to 9.1.20091.1000 while my main project was pointing to 9.1.20091.2023..
I dropeed all my references to 9.1.20091.1000 in may base project and made sure the new ones were pointing to 9.1.20091.2023.
