They did this quite a lot in the mid 90s. There was a lot of grief with various upgrades to Office, but it seems to have stopped in recent years. They may be evil (in the sense, your honour, of having been found to have behaved anti-competitively in some jurisdictions) but they're not stupid and they realised that the forced upgrade cycle at several hundred bucks a seat was a trick they could only pull two or three times, and the Word 97 format is still the de facto standard for business documents. I run it under Crossover Office and I've not yet had a problem not being able to open attachments from clients and associates running later versions. Which is why their main business objective is now to switch software from a purchase to a subscription model. Edward Barrow
