Required Input fields red & green & field history values

[schot]

I am not sure if I use the correct English terms, please feel free to correct!

 

Under Windows IE one of our customers is experiencing this problem:

 

1. Editing a value into an required input field which is checked for correct entry (like an email address). 
2. Typing an error value (for example, email address without '@')
3. Leaving the field (press 'tab' key), it turns 'red' (with X) indicating the value is wrong 
4. Going back to the input field (field stays red), selecting a previously entered value by the input field history dropdown, the field color stays 'red'.

 

Can this be corrected and if yes, how? After selecting the value, the field color should reset to default color.

 

On our Mac's with Firefox and Chrome, when you select a value from the input field history dropdown box, the field color is instantly reset to 'default'.

1. After you enter correct value, you have move your cursor out of the field, so that it will trigger the validation and it will remove red?

Yes, only leaving the field will revaluate the field contents.

It should revaluate the contents directly when a value is selected from the field history pull down list...

I think this is the way the validation was designed to work - only when you move out of the field, it will trigger the validation.
