Thank you. Yes, I understand the problem. But TortoiseSVN could still re-prompt, using this recipe:
1) Perform default authentication
2) Attempt the authz-requiring operation (e.g., commit)
3) If (2) fails, look at the exact error, and...
4) ...if it's an authz error, prompt again for new authn
credentials and continue as if from (1).
Even though authorization comes later than authentication, TortoisSVN can still remember things and link them together when it's appropriate to do so.

Ah, I didn't know about that, and it helps as a workaround. But there is a chance for TortoiseSVN to offer an even friendlier user experience here, I think, as described above.

Also useful as a workaround.

Even better, thank you.

It definitely helps to have these workarounds. But if you think the above proposed new behavior is a good idea, could we file an enhancement ticket in the tracker? I realize maybe no one has time to implement it right now (and I have zero Windows development chops, unfortunately), but at least having the ticket filed provides a starting point, and would give people something to refer to.
