Is there any way to incorporate basic spell check functionality into PPM text fields?
In current PPM versions this is not posible. I mean PPM doesn't have a feature to accomplish this.
However, there are a couple of enhancement request created and this feature will be inlcude in the next PPM release:
QCCR1L39939 Spell check in PPM fieldsQCCR1L37644 Spell Checking capability
Both of them have been approved to be inlcude in the coming version.
