Sometimes I move too fast, but I think I narrowed down the issue to this: I can use all of my usual formatting, but am limited to ONE table per post, not TWO - or I can just omit [b] tags from the tables. Either works, but once I try to combine them, bad things happen.
The following code cannot be posted successfully:
[table][tr][td][right][b]Table 1[/b][/right][/td][/tr][tr][td]Row 1[/td][/tr][tr][td][right][b]Row 2[/b][/right][/td][/tr][/table]
[table][tr][td][right][b]Table 2[/b][/right][/td][/tr][tr][td]Row 1[/td][/tr][/table]
Ah - so to add a second row with [b] breaks things... interesting.
