Hi, all,I've recently reinstalled LyX 1.3.6 (on Mepis linux, 2.6.12 kernel; the problem also implies to 1.3.6 on a Kubuntu installation) after a hdd crash. When run through latex, documents containing \implies produce the dreaded "Undefined control sequence" error. However, instant-preview shows the danged thing just fine. Using \rightarrow works just fine for me; should this be filed as a low-priority bug? I guess I could just define \implies as \rightarrow in the preamble, right? Many thanks, Curtis O.
Do you have the "Use AMSMath" box checked in Layout->Document->Packages? Lack of that would explain "undefined control sequence" (but would not explain preview working).
