Anomalous X-ray Pulsars (AXPs) are now established to exhibit significantX-ray variability and be prolific glitchers, with some glitches beingaccompanied by large radiative changes. An open issue is whether AXP glitchesare generically accompanied by radiative changes, relevant for understandingmagnetar physical properties. Here we report on an analysis of archival X-raydata from the AXP 1E~1841$-$045, obtained between 1993 and 2007. This AXP,located in the center of SNR Kes~73, has exhibited three glitches between 2002and 2007, as determined by {\it RXTE} monitoring since 1999. We have searchedfor evidence of phase-averaged flux variability that could be present ifglitches in AXPs are usually accompanied by radiative changes. We find noevidence for glitch-correlated flux changes from this source, arguing that suchbehavior is not generic to AXPs.
