How in the world can Rational not allow period char when creating new builds? Example - In Test Manager from the menu select tools \ manage \builds. Creat a new build and it will not allow 1.0 or 1.1 This is very common software identification they should have their heads examined for not allowing this. How are some of you identifiying your builds? We will probably use 1a, 1b, 2a etc.... Called their support and they aknowledge this issue but have no fix.
